  1. Water Quality Observations 2009Algae Blooms

  2. Upper River Taste and Odor Reports • Initial report to ORSANCO on June 1, 2009 • Complaints from: • Toronto, OH (ORM 59.2) • Weirton, WV (ORM 65.2) • Steubenville, OH (ORM 65.3) • Wheeling, WV (ORM 86.8) • Later confirmed at East Liverpool (ORM 40.2) and Midland (ORM 36) • T&O problems started on May 28. • Weirton reported clear water on June 1. • Beaver Falls, PA water plant reported T&O problems on May 26 • Conference call with PA DEP on June 5

  3. Sampling Locations • Samples collected on June 8, 2009 • Nutrients (TP, TKN, Nitrate/Nitrite, Ammonia) • Algae community • Dashields L&D (ORM 13.3) • Beaver River (Confluence at ORM 25.4) • Montgomery L&D (ORM 31.3) • New Cumberland L&D (ORM 54.4) • Pike Island L&D (ORM 84.2) • Wheeling Water Plant (ORM 86.8)

  4. Nutrients Sample Results

  5. Algae Sample Results

  6. Lessons Learned and Future Planning • Algae issues are usually very short lived • Response time important • Second time in 3 years we have seen spring time algae issues on the upper river • Preparation for 2010 • Sampling kits for water treatment plants • Discussed Hydrolab placement with L&Ds

  7. Microcystis Bloom Middle River • Cincinnati Area (ORM 451-470) • September 22- October 5 • Contacted Louisville and Huntington Water Plants • Visual observation of near shore Microcystis in Louisville • No reports of T&O problems • Concentration greater near-shore • Avg. near shore 1,243 colonies/ml • Avg. mid river 247 colonies/ml • Toxicity testing not yet available

  8. Nutrients Analysis 2009

  9. Algae Analysis 2009 (Near shore vs Mid River)

  10. Flow Comparison 2008-2009

  11. Temperature Comparison 2008-2009

  12. TP at ORM 463 Comparison 2008-2009

  13. Conclusions from 2 years of blooms • Literature suggests temperatures greater than 25 C needed for Microcystis to bloom • Light penetration needed to start recruitment of spores from sediment • Water column nutrients not a limiting factor – sediment nutrients sufficient • We could have a Microcystis bloom any time the temperature and clarity coincide.
